Visual Studio's "Watch" Window

One of the cool and not-so-well-known features of the Visual Studio Watch window is that it not only lets you read and modify values, but also evaluate arbitrary expressions on the system. In one of my current projects, I am doing a significant amount of rendering to a Bitmap prior to blitting it to the screen. If there's a bug in the rendering, it can be quite difficult to track down what the issue is with just a Watch window. It would be a lot more helpful to actually see the contents of the Bitmap as you are rendering it. And you can, by typing in the expression to save the bitmap out, while execution is halted! For example:


After typing that in, you can just go to the directory where the image was saved and inspect it. Very useful trick. If you have any of your own, please share!
